Chrysanthemum plant named ‘Yoadelle’

ABSTRACT

A new  Chrysanthemum  plant named ‘Yoadelle,’ particularly distinguished by the small single white spoon shaped ray florets, compact and short, uniform habit with excellent branching, and dark, glossy small foliage.

Latin name of the genus and species of the plant claimed:Chrysanthemum×morifolium.

Varietal denomination: ‘Yoadelle’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Chrysanthemum, botanically knownas Chrysanthemum×morifolium, and hereinafter referred to by the varietyname ‘Yoadelle’.

‘Yoadelle’ is a product of a planned breeding program. The new cultivarhas small single white spoon shaped ray florets, compact and short,uniform habit with excellent branching; dark, glossy small foliage.

‘Yoadelle’ originated from a hybridization made in February 2004 in acontrolled breeding environment in Salinas, Calif. The female parent wasthe proprietary plant designated ‘YB-A0900,’ unpatented, with whitedaisy spoon flowers. ‘YB-A0900’ has more floriferiousness, is taller andhas a less compact habit than ‘Yoadelle’.

The male parent of ‘Yoadelle’ was the proprietary plant designated as‘YB-A7015,’ unpatented, with white anemone spoon flower form. ‘YB-A7015’has less floriferiousness and a less compact habit than ‘Yoadelle’.

‘Yoadelle’ was selected as one flowering plant within the progeny of thestated cross in February 2005, grown outdoors in a field covered bysaran in Fort Myers, Fla.

The first act of asexual reproduction of ‘Yoadelle’ was accomplishedwhen vegetative cuttings were propagated from the initial selection inMay 2005, in a controlled environment in Fort Myers, Fla.

Horticultural examination of plants grown from cuttings of the plantinitiated in May 2005, and continuing thereafter, has demonstrated thatthe combination of characteristics as herein disclosed for ‘Yoadelle’are firmly fixed and are retained through successive generations ofasexual reproduction.

‘Yoadelle’ has not been observed under all possible environmentalconditions. The phenotype may vary significantly with variations inenvironment such as temperature, light intensity and day length.

A Plant Breeder's Right for this cultivar was applied for in Canada inOctober 2008. ‘Yoadelle’ has not been made publicly available more thanone year prior to the filing of this application.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical flower and foliagecharacteristics of ‘Yoadelle’ with colors being as true as possible withan illustration of this type. The photographic drawing shows 3 floweringpotted plants of the new variety, with a close-up of the flowers.

DETAILED BOTANICAL DESCRIPTION

The plant descriptions, measurements and aforementioned photographs weretaken in Gilroy, Calif. in April 2009, under greenhouse conditions. Theplants were started and grown in central coastal California, grown underconditions which approximate those generally used in commercial pottedChrysanthemum production and were about 8-9 weeks of age when shipped toGilroy, Calif. in April 2009.

Color references are made to The Royal Horticultural Society ColourChart (R.H.S.) 2001.

BRIEF SUMMARY OF INVENTION

The following traits have been repeatedly observed and are determined tobe basic characteristics of the new variety. The combination of thesecharacteristics distinguishes this Chrysanthemum as a new and distinctvariety.
